With search engines, I can find supposedly dustproof screen protectors for sale? e.g.: http://www.amazon.ca/Clear-Scratch-Resistant-Screen-Protectors/dp/B003JBRSXY http://www.amazon.com/Apple-iPhone-Protector-Washable-Resistant/dp/B00A2A0D7S
Do these screen protectors actually repel dust? Do they actually end up less dusty than other screens/screen protectors?
